' COMBINATION CHAMFER AND BUTT GAGE- I I'at'entedDec. 5, 1 905:

Application filed August 21, 1905. Serial No. 275,037.

To all whom it may concern.-

'Be it known that I, FREDERIOKH. LooK- WOOD, a citizen of the-United States, residing at Alameda, in the county of Alameda and State of California, have invented new and useful Improvements in Combination Chamfer and Butt Gages, of which the following is a,

specification;

My invention relates to an improved car penters gage, and" especially to a combined butt and chamfer gage. I

In gaging or marking the butting faces of door-jambs and doors where the butthinges are to go it has often heretofore been a matter of difficulty to work in the narrow angles allotted by the door-jamb and wall construction. It is essential to the true hanging of the door that the butt-gaging be done from the front or the side toward which the door opens. If it is attempted to gage the butt-cuts from the wooden stop on the jamb and against which the door closes, the door is liable to be hung crooked, especially where there are a number of similar doors in a building to be hung, by reason that the doors will all vary more or less in thickness. Also it is a matter of inconvenience and loss of time in carpentry with the usual single-point gages in marking the corners for future chamfering of square posts, pillars, and the like.

The object of my invention, then, is to provide a gage which can be used for gaging butts from the inside of the door no matter how confined or cramped the space'or what ledges may interfere, which will gage and mark both the width and thickness of the cut at one operation, and which will gage and mark both sides of .a post or the like for chamfering; and, moreover, it is my object to make such a tool which shall be neat, durable, practical, and compact and which may be carried easily in the pocket.

It'is also my object to provide a gage for making two parallel marks on the same flat surface at one operation:

Theinvention consists of the parts and the construction and the combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a side view of my gage.

2 is a plan view of Fig. 1. Fig. 3 is an end device.

Fig.

The drawings represent a practical full-size This stock has a longitudinalgroove or slot 2 along its bottom. The opposite walls are concaved to form a guideway and housing for a gage-beam or sliding piece-3 carrying the marker 4: at one end. This sliding piece has a vertical groove or concavity in its end, and the marker has a corresponding convexity, so thata single screw serves to hold the marker removably to the piece 3 and at the same time the marker is prevented from turning. The marker is'slottedso that as it becomes worn or dull it may be dropped downor removed and sharpened or provision made for a deeper or shallower mark or cut, the groove 2 being deep enough to accommodate the endof the marker, which may project above the sliding piece. The stock is perforated at right angles to groove 2 to receive a second beam or sliding piece 5, which carries a similar marker 6 at its marking end,

secured in the same way as marker 4:. If de-. sired, the sliding piece 5 may he graduated as shown at 7 and the bottom of the stock A from the piece 5 may be graduated as shown at 8. In order to adapt the gage to mark two parallel lines on the same plane surface,- as it is sometimes desired to do in carpentry, I may provide a second sliding piece 5, arranged parallel with the sliding piece5 and locked in any desired position by a set-screw 10. The sliding piece 5, like the piece 5, is made round and carries a removable adjustable marker 6.

If desired, the piece 5 may he graduated, as

shown at 7 By turning the pieces 5 5 in the position shown in dotted lines, Fig. 1, they may be used conjunctively to draw two parallel lines on the same flat surface, or either one of the pieces 5 or 5 may be used in conjunction with the piece 3 where it is desirable to mark two sides of any rectangular object, as in marking corner-posts for chamfering. Only one of the pieces 5 or 5 will be used at the same time with the piece 3, that piece 5 or 5' which is not in use being temporarily removed, if necessary, by having the marker members 6 constructed in the fashion shown and arranged directly on the ends of the sliding pieces.

The device is capable of being worked in very shallow angles.

It is possible that various modifications in my invention may be made Without departing cific construction shown and described.

Having thus described my invention, what I claim, and desire to secure by Letters Patent is 1 A combination chamfer and butt gage comprising a body portion having two gage-w ing a convexity fitting the concavity in the end of the sliding piece, and a screw fitting the slot in said marker and perforation in the end of the sliding piece.

3. A gage comprising a body portion and an adjustable sliding piece carried thereby,

said sliding piece having its end transversely concaved, and a slotted marker provided with a corresponding convexity to fit said concavity and lock the screw to hold the marker to the sliding piece.

4:. A gage comprising a body, two sliding pieces carried thereby and adjustable and turnable therein and parallel with each other, and a third marking-piece carried by the body and arranged at right angles to the first-named sliding piece, and markers carried by said sliding pieces, said third marking-piece having a recessed seat in its end and one of said markers being slidably and non-turnably seated thereon, and means securing the last-named marker in position.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
